* <h2>Compilation with Visual C++ (Express and better)</h2>
*
* We provide a project for Visual C++ 2008. You can select 3 Types of Compilation:
*
* <h3>Executable (Release or Debug)</h3>
*
* This will compile the code as an executable which can lookup strings from every .mo-File you load with it.
* This can be handy if you want to have a peek into a file or test something etc. I recommend building the
* release-executable only if you just want to use it.
*
* <h3>Dynamic Loaded Library ( ReleaseDLL )</h3>
*
* This may be overkill, but perhaps you like it modular. This Configuration will create a dll and an import-library.
* Do not forget to link against the import-library and please define MOFILE_IMPORT in your preprocessor-settings,
* otherwise you will receive a bunch of linker-errors.
* You will find all files in the directory "lib" in the Solutions Directory.
*
* <h3>Static Library ( ReleaseLIB )</h3>
*
* This will compile the code as a static library with no Entry-Point. This is the recommended usage.
* But please do not forget to link against moFileReader.static.lib. Otherwise you will receive linker-errors.
*
* <h2>Compilation via cmake</h2>
*
* - Make sure you have cmake installed and in your path. If not, go to http://www.cmake.org and get it.
* - Make sure you have cmake installed and in your path. If not, go to http://www.cmake.org and get it.
